Maze

A man is in a maze, suddenly the power shuts off. He walks on and it gets colder and colder. He comes to a set of doors numbered 1, 2, 3 and 4. He walks through door 3. Then, he comes to three more doors labeled A,B, and C. He goes through B and it locks behind him trapping him so he cannot turn back. In front of him are two doors. In one is a loaded gun that will shoot him and the other contains an electric chair that he will be strapped to. Which one should he choose?
